A highly selective method for the asymmetric formation of trifluoromethyl-substituted α- and β-aminophos- phonates was described. The reaction proceeded with high yields and good to excellent diastereoselectivity. The product can be easily converted into corresponding trifluoromethyl-substituted aminophosphoric acids.
An efficient and cost-effective method for the preparation of fluorinated conjugated enynes was described, tile method was compatible with a variety of functional groups such as chloride, amine, cyano and ester group. The method could also be extended to the coupling of （R,Z）-3-（2-chloro-1,2-difluorovinyl）-4-alkyloxazolidin-2-one （3） with moderate yields.
